SPRING WINDING MACHINE.

Application filed November 20, 1925.

This invention relates to winding machines and in particular to a type adapted to wind devices wherein are embodied springs, which require considerable winding in order to coil the same into operating position.

The particular object of the invention is to provide an efficient machine and a plurality of chucks therefor, which can be used to wind up a series of spring operated devices such as toys, window shade rollers and the like.

A further object of the invention is to so'construct the machine that it canbe set up in any desired position and can be operated by hand to efliciently wind up a device embodying a spring.

A further object of the invention is to construct a machine of this character which will have few parts, can be manufactured at a small cost and which willlast indefinitely. A further object'of the invention is to provide a number of chuck pieces which will engage the parts of the device to be wound, which carries the spring whereby said 0 spring may be wound by a turning movement of the chuck, the machine being arranged to multiply the speed of winding,

which is originallyimparted to the machine,

by an operator.

Referring to th'e drawings, wherein a prefcrrcd'embodiment of our invention has been shown; v

Figure 1 is a view in front elevation of a machine constructed in accordance with our idea, the face of the chuck carried by said machine being shown.

Figure 2 is a view in vertical section taken on the line 22 of Figure 1 and shows the interior section of the machine and illustrating how the power applied thereto by an operator is transferred tothe chuck to perform the winding operation.

Figure 3 is a. face view of a chuck, used. for winding up the end of a window shade roller or the like.

F iguret is a section taken on the line 4-4 of Figure 3, showing the shape of the slot in the chuck.

Figure 5 is a face'view of a modified form of chuck having a conical depression therein which renders the placing of the device to be wound possible with a minimum of time and effort.

Figure 6 is a section taken on the line 66 of Figure 5. i

rotation of the chuck contrary to the winding movement, and

Figure 10 is a section taken on the line 10-10 of Figure 9 showing the construction of the chuck.

Referring to the drawings in detail, 5 ining portion 6 in which is threaded the screw 7, carrying at its upper end the jaw 8 and at its lower end the finger piece 9, the jaw 8 being adapted to engage the under side dicates the machine frame, having a dependof a table edge 10 uponthe top of which rests the projected foot portions 11 which are formed integral with the frame 5. The upper portion of the frame is formed to provide a circular'housing 12, having cast therein at its center, thehub 18, in which is journaled the drive shaft 14, which carries at'its outer end, theoperating handle 15, the handle being suitably held thereon through the medium of the nut 16.

The inner end of the shaft 14 is threaded as at 17 and carries thereon a driving gear 18, which is positioned on said driving shaft between a collar 19 and a lock nut 20, the face of the housing 12 is closed through the medium of the snap cover 21 which is'held in place at its lower end by the fixed ph 22 and engages at its upper end in the notch 23 formed in the under side of the housing 24 which is cast integral with the housing '12 at the top thereof. The housing 24 is closed through the means of the cover 21 and supports therein the stub shaft 26 upon which is mounted a pinion 27 in engagement with the gear 18 and driven thereby, the stub shaft 26 being squared at its for ward end as at 27 to receive a chuck 28.,

the chuck being held in position by a set screw 29.

Operation of the handle 15 will, through the gear 18 and pinion 27, revolve'the stub shaft 26 at a high rate of speed, so that the chuck 28 will revolve rapidly and thereby wind up the spring in any device having a spring carrying or winding element. In

Figure 9, we have illustrated the end of a shade roller 30. the spring shaft thereof being indicated as at 31 and through the medium of which, the spring of the shade roller, not shown, is wound.

In the chuck 28, we have shown an uudcn cut slot 32 into which is slid the face plate 33 and held therein by the screws Set, the center of the face plate being raised as at 35 and being cut to provide a cross-shaped slot 36 into which the end bl ot the shade roller shalt can be inserted. By making this crossashaped slot oi such 'lorination, no adjustment of the handle to will be necessary in order to brine the chuck into position for insertion oi the end of the shade roller shaft, thereby saving time and ad justinent oi the shade roller relative to the chuck 28. In order to adapt the machine foruse in winding up various devices, we provide therefor, a plurality of chucks and in Figures 3 and l, have shown a chuck cinhodying a cross-shaped sloti-lT. the sides of which are tapered as at 38 to allow yor various thicknesses of the end oi? spring winding shafts. such, for instance, as the linger pieces used on mechanical toys to wind the SHIIJE up.

In Figures 5 and 6, we have shown anothcr form of chuck having} a depression 39 therein, at the bottom of which is provided. the cross-shaped slot 40. This depression 39 is tapered so that when the end of a spring shaft is placed thcreagaiust, it will automatically find its way into the crossshaped slot 4-0.

In Figures 7 and 8, we have shown a chuck el-l having fastened on the taco thercof a. slotted plate, which functions some what after the manner of the chuck illustrated in Figures 5 and 6, the plate 42 having a depression 43 therein and also a crossshaped slot l i.

In Figures 9 and 10, we have shown a. chuck in the nature of a cup 45 having two cant-like pieces. set therein and being so cutand shaped that they will provide a slot 4:7 between them into which may be inserted the end of a shaft to be wound. The opposite diagonal parts l8 and ll) of said pieces being; sloped downwardly so that if the chuck is given a reverse rotation. the spring shaftindicated as at will ride up on the pieces and will not be unwound. These chucks may be placed on the end of the driven shaft by any suitable means. It will be evident therefore, that we have provided a machine which may be used with a number of chuck pieces for use in winding up the spring operated toys, roller shades and in winding the springs themselves about a mandrel during uianut'actin'e. and a machine which will multiply the power 0t an operator and will wind the devices, toys or the like rapidly and ellicicntly. tl'lerehy reducing the cost of the articles with a resulting benefit to the users.

.rilso it; will be evident that we have provided a machine, which can be set up in any desirable position or place, such, for instance, as in the toy department, 01": stores where incclninically operated toys have to be wound for dernonstration and in any other place. such as in a shade roller manufacturing plant: where springs are wound up so that the shade roller will have the proper adjustment when placed in position.

lVhile we have illustrated and described our invention with some degree of particularity, we realize that in practice various alterations therein may he made and theretore, we reserve the right and privilege oi changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing" from the spirit 01? the invention or the scope of the appended claim.

Having thus described our invention, what we claim as new and desire to secure by United States Letters Patent is The combination with a. machine having a driven shaft and a speed multiplying gear arrangement of a. chuck secured to said shaft, said chuck having a cross-shaped slot therein for acconnnodation of a shalit end to be wound, and a conical depression in said chuck whereby the shalt end may he guided into said slot.

In testimony whereoit we atlix our signat-urcs.
